The primary object of the invention is to the equalizing bar indicatedat 10. I have provide improved, simple and efficient means shown a wireconductor 12 attached directly to plate 9 and designed to conduct theourfor supplying current to the car motor from rent from the latter tothe car motor. De-

So far as I am aware, the broad idea to pending from either end of theplate 9 is an which my invention relates has failed of uniarm 13.
